Firsov left the family and soon left for one of

Firsov left his family and soon left for one of the regions of the Far North. After returning to Ekaterinburg three years later, he went to court with a lawsuit against Firsova about the dissolution of the marriage and the division of jointly acquired property: a furniture set, piano, TV, refrigerator, VCR and a valuable collection of old medals, which, although his wife got it, inherited from his father, but was significantly replenished by Firsov during their life together.
Firsova at the hearing did not mind divorce, because the family had long since broken up. Things were purchased mainly with her money. Therefore, even before her husband left the family, she told him that things belong to her and he won’t get anything. All four years of marriage, her husband did not give her her salary, but spent it on personal needs, often left the family, in connection with which she was already forced to collect child support from him already. He really added to the collection, but Firsova considered it hers and therefore, after her husband left the family, she sold it to her neighbor Loktev; she bought the piano on credit after breaking with Firsov and still pays for it. In addition, Firsova filed a counterclaim to recover 2000 rubles from the defendant. Before leaving, Firsov borrowed this amount from their acquaintances, Semenov, supposedly to buy the piano, leaving a receipt that he or his wife would repay the debt in six months. Firsova was forced to pay this money, which she knew nothing about before.
